Let it sit for 5-10 minutes, some timeouts can be pretty long (tpm related ones come to mind, 6 minutes…) - hopefully something gets logged by then (the boot log up to that point is not overly conclusive). Make sure to test an untainted kernel as well, as binary modules like nvidia make debugging impossible.

I waited 2 hours but it just froze, hard reset is required (holding power button).
I removed the proprietary nvidia driver, still the same.

I will try a live-cd with the latest kernel.

Tested with the latest 2011-3 live-CD and still the same behaviour.
If i disable local ACPI the system boots.

It basically suggests the real answer is to update your bios (though the thread offers "alternatives" to acpi=off which might work as temporary workarounds).

Disabling ACPI is critically dangerous on modern systems and notebooks in particular, not only do you lose all cores but one, there is a serious overheating risk with ACPI disabled, which might result in permanent hardware damage.
